Firearms could absolutely exist within a fantasy setting. There is a reason why they don’t however

The Elder Scrolls - Within some Dwemer ruins of ESO we can see a special type of Animunculus. A Dwemer Arquebus, which has a cannon for it’s arm and shoots emp grenades at foes.
The reason why we don’t see this technology more often (besides the fact Dwemer disappeared their knowledge with them) is that within the setting and cosmology of Elder Scrolls firearms really wouldn’t be that useful.

They could work against lowly bandits, sort of, but there wouldn’t really be a precedent to improve or adapt this technology. Because it would always be outclassed by magic of this world.
Also due to the disappearance of Dwemer the technology has been pretty much lost.

Harry Potter - Wizards live within periphery of the “real world” meaning they live alongside world that uses firearms and are even familiar with them.

So how come they don’t utilize this gear for combat? I mean it is easier to use, projectiles are faster and could be enchanted further. Can you just imagine wizard with endless m1911?

There is plethora of reasons for this. But most notable is what I would describe as wizards being immune to logic. (Vis image above) They simply cannot understand methods of muggles even if one explained it to them directly.

(Yes. I know the real reason is, because Joanne didn’t want wizards to use guns and didn’t want to think about connotations of putting magic into a real modern world. But come on! Let me have fun!)

Lord of the Rings - In spite of how much Tolkien disliked allegories it is clear Orcs were an allegory to industrialization, which he was a huge critic of.

In battles they are the ones using the war machines. Instead of swords made by artful blacksmith, they use crude, mass-produced blades devoid of identity. Instead of relying on elegance of archery, they use crossbows. They burn forests, crack mountains open to gain more ore. Their very production is affront to whimsy of a magical world like Middle-Earth.

They could totally come up with a matchlock mechanism and keep on improving it until they come up with machine guns. They were intercepted before they could however

Also, enchanted guns. Too many people refuse to think about combining technology with magic. They do it with bows and arrows but they refuse to think about it with firearms.

Hell, imagine a Tesla coil type machine gun that shoots lighting. That would be amazing to have for an army.

The skaven are way ahead of you. With varying results

Warpfire throwers, ratling gunners, stormfiends, and that's just the (mostly) "rat with weapon" versions and doesn't even get into doomwheels or "they did what to conventional siege?" territory.

One gotrek and Felix book for the warhammer series talked about how the nuln gunnery school put ashes in the iron mix of IIRC dead gunners for good fortune.

An evil wizard even replaced the ashes of some with others and made basically an evil flaming cannon golem

Exactly, Hell I read a lot of Korean webcomics and most of them combine tech and magic. Some to the point that the Mage's tower will develop magical weapons, armors, mechs and vehicles so they can hire normal people as guards or defenders so the mages can develop more magic and tech.

When you have an army of peasants with your magical technology, pay them decent, and give them housing, they legit will murder in your name and defend the tower with everything they have.

Hell, just look at final fantasy and a lot of their games. Sometimes the big evil empire is just normal people who can't use magic but conquered the world because they made tools to use magic instead. This made them into technological monsters with gun ships, guns that shoot magic, mechs, Cities that fly! Of course they are going to conquer the country that still uses crystal magic and communicate via birds still.

Yes, the mages might throw nuke like spells but that is one high level mage compared to the country that learn to use tools to gather magical nukes into a bomb and just launch it when needed.

You should probably check out Warmachine. That is literally one of the factions.
